The company that embeds the videos should consider how said media is presented to it's users. It is a weird concept yes I know. Just try to contemplate it.
It depends on how you view a website-browser relationship.
If you believe your browser displaying a site is under third-party control, then yes, it's third party that's responsible for presentation issues. If you believe since something running in your browser then you and browser vendor are responsible for presenting the contents in a manner you want it, then, well, it's another way.
Actually, I think one should complain to both companies.
Outside frames are called parent for a reason. I'm pretty closed book on how I feel about the issue. Though I agree both should be complained to, just that responsibility falls on those who embed.
I really thought we made it past the auto-play era of the 90s.
